+Usage
+=====
+
+Gimmecert provides a simple and clean CLI interface for all actions.
+
+Description of all available commands, manadatory arguments, and
+optional arguments is also made available via CLI by either using the
+help flag (``-h`` / ``--help``) or help command.
+
+Running the tool without any command or argument will output short
+usage instructions listing available commands.
+
+To get more detailed general help on tool usage, and list of available
+commands with short description on what they do, run one of the
+following::
+
+  gimmecert -h
+  gimmecert --help
+  gimmecert help
+
+To get more details on specific command, along what mandatory and
+positional arguments are available, simply provide the help flag when
+running them. For example::
+
+  gimmecert init -h
+  gimmecert init --help
